The crofter's wife went into labor in the middle of the night, and the doctor was called out to assist in the delivery. To keep the father-to-be busy, the doctor handed him a lantern and said: "Here, you hold this high so I can see what I'm doing."

Soon, a lusty baby boy was brought into the world.

"Och!" said the doctor. "Don't be in a rush to put the lantern by...I think there's yet another wee bairn to come."

Sure enough, within minutes he had delivered a bonnie lass.

"Na, dinna be in a great hurry to be putting down that lantern, lad...It seems there's yet another one besides!" cried the doctor.

The crofter scratched his head in bewilderment, and asked the doctor: "Well, now, mon. Do ye suppose the light's attracting them?"
